Because gold is an unreactive element, there is a limited number of compounds in nature, it can be free or associated with other mineral phases, such as sulfides.Among the metallurgical processes exists the recovery of values due to adsorption and desorption of activated carbon.
Leaching of gold ores with dilute cyanide solutions and the recovery of gold and associated silver from the pregnant effluents by a carbon adsorption- desorption method.Mineralogical considerations, experimental work, field studies, and commercial operations are described.Also presented are recent.
Carbon adsorption in recovery of gold from cyanide leach solutions.It has been known that gold in a cyanide leach solution would adsorb to activated carbon for over 70 years, and many papers have been written on the subject.Carbon, as a media of recovery for gold from leach solutions, did not gain wide acceptance in the gold industry until.
Metals involve the adsorptive recovery of gold and silver from cyanide media in a so-called carbon-in-pulp cip process in the gold industry 11.Extensive research works have been conducted in this area 2-6.Activated carbon is a good adsorbent as it has an extended surface area, porous structure, high adsorption capacity and a certain degree.
Mohansingh 2000 studied the adsorption of gold onto ac by varying parameters and varying the concentration of different species in solution and found that gold from copperammoniumthiosulfate solution did not adsorb well onto ac and the maximum adsorption capability of gold on ac was 0.267 kgt 1 ac by calculation.
